Magazines and journals that cover a wide range of scientific disciplines.
Human and animal behavior, social and community relationships - psychology, sociology, anthropology, archaeology, ethnology, linguistics, learning, perception, urban problems, reading problems, educational testing, etc.
Chemistry of life processes - molecular biology, molecular genetics, enzymes, photosynthesis, protein chemistry, food chemistry, hormones, etc.
Study of plant life - agriculture, agronomy, horticulture, forestry, plant taxonomy, plant physiology, plant pathology, plant genetics, hydroponics, algae, etc.
Study of nature and the composition of matter and laws governing it - physical chemistry, organic chemistry (other than biochemistry), inorganic chemistry, materials, plastics, fuels, pesticides, metallurgy, soil chemistry, etc.
Study and development of computer hardware, software engineering, internet networking and communications, graphics (including human interfaces), simulations/virtual reality, or computational science (including data structures, encryption, coding, and information theory).
Geology, mineralogy, physiography, oceanography, meteorology, climatology, astronomy, speleology, seismology, geography, etc.
Technology; projects that directly apply scientific principles to manufacturing and practical uses - civil, mechanical, aeronautical, chemical, electrical, photographic, sound, automotive, marine, heating and refrigerating, transportation, environmental engineering, etc.
Study of pollution (air, water, and land) sources and their control; ecology.
Development of formal logical systems or various numerical and algebraic computations and the application of these principles - calculus, geometry, abstract algebra, number theory, statistics, complex analysis, and probability.
Study of diseases and health of humans and animals - dentistry, pharmacology, pathology, opthalmology, nutrition, sanitation, pediatrics, dermatology, allergies, speech and hearing, etc. Note: Gerontology, the study of the aging process in living organisms, is a separate ISEF category. Such projects would probably be placed in Medicine and Health at the GSDSEF.
Biology of microorganisms - bacteriology, virology, protozoology, molds, fungi, bacterial genetics, yeast, etc.
Theories, principles, and laws governing energy and the effect of energy on matter - solid state, optics, acoustics, particle, nuclear, atomic, plasma, superconductivity, fluid and gas dynamics, thermodynamics, semiconductors, magnetism, quantum mechanics, biophysics, etc.
Study of animals - animal genetics, ornithology, ichthyology, herpetology, entomology, animal ecology, paleontology, cellular physiology, circadian rhythms, animal husbandry, ctyology, histology, animal physiology, invertebrate neurophysiology, studies of invertebrates, etc.
(Junior divison only) Quality control, comparison studies of product designs using accepted engineering tests to obtain quantifiable results, etc.
